About Us

M.J. Mac Inc. was established in 2007 by Jay McIntyre.

After working for other companies a total of 15 years, Jay wanted to start his own company. He believes in building strong business relationships with customers, having some as long as 8 years or more.

Jay’s dedication to his customers is apparent through his 24 hour Emergency number. Jay does not charge any Over-Time or Service Fees.

Jay has built his company from the bottom up. Building his crew of employees, as well as personally over-seeing, and involving himself with all aspects of the business. M.J. Mac was founded on good old hard work and dedication. All M.J. Mac Technicians are as hard-working and dedicated as Jay himself.

In his free time, Jay enjoys spending time with his wife of 8 years, Kristina, as well as his 4 boys.

M.J. Mac is a proud provider of service and installation to any and all of the tri-state area’s residential and commercial HVAC and refrigeration needs. We are an RSES Member, EPA Certified, and in compliance with the Clean Air Act of 1990.
